TENSlGN DEVlCE FOR SILK-TWISTING MACHINES.

SPECIFECATION forming part of Letters Patent No. 359,184, dated March 8, 18 87.

Application filed September 8, 1886. Serial X0. 212,988. (No model.)

T all whom, it may concern:

Be it known that I, GEORGE SING LETON, a citizen of the United States, and a resident of Dover, Morris county, State of New Jersey,

have invented certain new and useful Improvements in Tension Devices for SillcTwisting Machines, of which the following is a speciiication. 4

My invention is designed especially for use on silktwisting machines; but it is applicable to other machines where a smooth, uniform tension is required.

It consistsin an armed plate attached to the rail of the machine between the spindle-bobbin and the receiving bobbin or spool, and around and about which plate and its arms the strand is wrapped in a manner to avoid crossing and consequent rubbing or abrasion in its passage from one bobbin to the other.

In the accompanying drawings, which form part ofthis specification, Figure 1 represents in sectional elevation a portion of a silk-twisting machine with my invention applied thereto. Figs. 2 and 3 represent my tension-plate in its simplest form; and Figs. 4 and 5 repre sent modifications in the construction of the same, Fig. 5 showing a plate with a multiplicity of arms, which is designed to give a higher tension than the forms illustrated in the other figures.

A represents the frame of a silk-twisting machine; Z), the spindle; b I), the driving-cylinder and its belt; (I. the rail of the machine; 0 the guide-rods; 0", the traverse'bar, c, the receivingbobbin andcthedriving-roll. These parts, being all of the usual construction and arranged according to the usual relative arrangement, require no detailed description.

0 represents my tension-plate, which is at tached to the rail (1 ol' the machine. It has a series of radiating arms, 0. l'our being found sufficient for ordinary purposes; but any numbcr may we employed.

The strand is wrapped upon or around the plate 0 and its arms 0, as illustrated in Fig. 2, more or less turns being given, according to the amount of tension required. As illus trated, the strand passes from the spindle-bobbin 0 to the tension-plate G, first touching the 50 latter at the point 1, thence passing over the top to the point 2, thence under to the point tension-plate crosses or too ches itself, and hence all liability of knotting or abrading is avoided and a superior product is the result.

The tension-plate 0 must have a perfectly smooth surface in that part over which the strand passes, and it may be made of any suitable material capable of receiving a smooth finish-such as metal, glass, &c., or any ma terial coated with these or other suitable substances. It may be made in one piece, as illus trated in Figs. 3 and 4, or in two or more parts screwed or otherwise secured together, as illustrated in Figs. 2 and 5. It may be attached to the rail of the machine by means of an integral screw, as in Fig. 4, or by screws or nails passing through holes, as in Figs. 2, 3, and 5. These details of construction, being imniate rial, may be varied at pleasure without departing from the spirit of my invention.

Having thus described my invention, I claim- 1. The tension-plate for silk-twisting and other machines herein described, consisting of a body portion adapted to be attached to the rail of the machine, and having at its outer or free end a series of radiating arms, upon and around which the strand is adapted to be wound, substantiall y as and for the purpose described.

2. The tension-plate for silk-twisting and other machines herein described, consisting of a body portion provided with an integral screw for attaching it to the rail of the machine, and having at its outer end a series of radiating arms, upon and around which the strand is adapted to be wound, substantially as shown and described.

In testimony that I claim the foregoing as my invention 1 have signed my name, in presence of two witnesses, this 3d day of September, 1886.

GEORGE SINGLETON.
